Kindly check attached image for question Two methods have been developed to determine the nickel content of steel. In a sample offive replications of the first method on a certain kind of steel, the average measurement (inpercent) wasand the standard deviation wasSxThe averageofsevenx = 3.16= 0.042:replications of the second method wasand the standard deviation was= 3.24S, = 0.048a) Determine if there is a difference in the mean measurements between the two methodand explain the most likely assumption that could be made before solving thisproblem?b) What informed your choice of solution method?

Here, Using hypothesis testing, we conclude that there is a difference in the mean level of nickel…

Two methods have been developed to determine the nickel content of steel. In a sample of five replications of the first method on a certain kind of steel, the average measurement (in percent) was = 3.16 and the standard deviation was The average of seven S, = 0.042· replications of the second method was and the standard deviation was y = 3.24 %3D S, = 0.048 a) Determine if there is a difference in the mean measurements between the two method and explain the most likely assumption that could be made before solving this problem? b) What informed your choice of solution method?
